Question
If a solution of sodium hydroxide is mixed from a 3M solution of sodium hydroxide, such that the volume of the original solution is 50ml and the volume of the final solution is 150ml, determine each of the following:
a. The volume of water added to the solution
b. The new concentration.
c. The mass of NaOH in both solutions.
a. The volume of water added to the solution
b. The new concentration.

you diluted it 3 times, so new concentration= .75M (you added one part orig, 2 parts water).
volume added: 100ml
Mass NaOH is the same in each.
.05*3 moles x 40g/mole
